Cybran have alot less less damage, and it can be sad to sometimes have sligtly not enought to finish a fatty.

T3 gunships for uef and cyb are pretty good, they can kill flack and t3 maa if you have enought gunships and can split them against flack. Any air unit would be fine against exp without flack.

What is better? I would say strats, cause they have nice damage and can avoid flack fire better.Tho for cyb i would use strats to kill aa and the use gunships to damage exp.In some situations gunships ca be good cause they avoid aa better... especially when exp is walking near water and protected by cruiser... But you can also abuse start ability to stop after bomb drop and turn around without flying above target
